On-chain delivery receipts for x402 AI-agent payments on Solana: anchors SHA-256 digests of delivered content to a PDA after settlement; buyers verify proof of delivery offline with zero trust in the seller. Live MCP endpoint + npm bridge.

Connects AI agents and developers to structured blockchain data across multiple networks through Nodit's Web3 infrastructure, enabling easy querying, analysis and interaction with blockchain ecosystems without specialized development expertise.

Enables interaction with the DorkFi lending protocol on Voi and Algorand, supporting market queries, user positions, liquidation scanning, TVL analytics, and transaction preparation.

A read-only MCP server that queries multichain EVM on-chain data through Blockscout REST API, providing tools for address info, transactions, logs, and more.

Enables AI-powered blockchain data queries and analysis through the Native Indexer (NIX) system. Supports querying blocks, transactions, account information, and network status across various blockchain networks.

Enables read-only, keyless queries of timestamped, definition-backed data about AI agent payments and activity on Base, including rankings, agent records, detections, metric histories, and evidence-pack pricing, from MCP clients or the terminal.

Enables AI assistants to securely interact with Fireblocks services through the Model Context Protocol, supporting transaction management, vault and exchange account queries, network connections, and workspace user management.

Made-to-order data for AI agents via x402 micropayments on Base. Describe a need in plain language, get a custom quote, pay per call. No signup, no API keys. HTTP + MCP transports. 5 tools.

This MCP server enables agents to fetch and reason about ERC-20 token metadata, balances, and allowances across multiple chains without hardcoding addresses or ABIs.

Enables querying indexed blockchain data via subgraph GraphQL queries, part of the Pipeworx MCP gateway.

Enables AI agents to query and analyze blockchain data from Dune Analytics, supporting execution of saved queries, ad-hoc DuneSQL queries, and access to cached results with parameter support.

Provides market data and user position information from earn providers like AAVE, enabling queries on APRs and deposits across multiple blockchain networks.
